EEALDON E. VATTON, OE ALTAMON'I, ILLINOIS, ASSIGNOR ONE-HALF TO GEORGEO. GOE'ITING, OFv SAME PLACE.

WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 438,042, dated October7, 1890.

Application filed June 13,1890.

To all whom it may concern.-

Be it known that I, FEALDON E. WATTON, of Alt-amont, in the county ofEffingham and State of Illinois, have invented a certain new and usefulImprovement in Window- Sashes, &c., of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.

My invention relates to a window sash, shutter, blind, or screen soconstructed that it may be adjusted to window-frames of different widthsand lit tightly therein; and my invention consists in features ofnovelty, hereinafter fully described, and pointed out in the claims.

Figure I is an elevation of my improved sash in position in the frame ofa Window. Fig. II is a detail side elevation, part broken away to showone of the plates. Fig. III is a similar view, in which but one plate isshown. Fig. IV is a cross-section taken on line IV IV, Fig. II. Fig. Vis a cross-section taken on line V V, Fig. II. Fig. VI is a detail edgeview of the upper end of the adjustable strip, showing the ends of theplates bentover upon the top of the adjustable strip. Fig. VII shows myinvention applied to a windowshutter, and Fig. VIII shows it applied toa window-screen.

Referring to the drawings, 1 represents a window-sill, 2 the sides ofthe frame, and 3 a window having the usual upper and lower bars 4 and 5and side bars 6 and 7.

Secured in the outer edge of the bar 7 are vertical plates 8, thatextend beyond the edge of the bar 7 and are provided with slots 9.

. 10 is a bar or strip equal in length to the bar7 and paralleltherewith. The bar has kerfs 12, in which the outer edges ofthe plates 8work, and thus the bar 10 is kept in the same plane as the sash, the barlO being secured to the plates by pins 1l, passing through the bar 10and slots 9.

The ends 13 and 14 of the plates 8 are preferably bent over upon theupper and lower ends 0f the bars 7 and 10, as shown in Fig. VI.

Coil-springs 15 are seated in recesses 16 in the upper and lower partsof the bar 7, and said springs bear against the strip l0 and Serial No.355,304. (No medal.)

press it outward. In order to increase or diminish the power of thesprings 15, their inner ends rest against the inturned end 15a of theplate 15b, the body of the plate occupying a recess in the sash andadmitting of endwise movement on a set-screw l5, which passes through alongitudinal slot l5d in the plate.

Secured in the bar l0 near its upper and lower ends are dovrei-pins orscrews 17,Whose outer ends work in holes in the strip 7. The dowel-pinsor screws may, however, be made fast in either bar.

In Fig. VII I have shown my invention applied to sliding shutters, suchas are used in the Windows of railway-cars and buildings.

In Fig. VIII I have shown my invention as applied to window-screens.

I have described my invention as having two plates 8 for connecting thebar 7 and strip 10; but in light windows, sh utters, and screens theremay be but one used, as I have shown in Fig. III.

The dowel-pins or screws 17 may be disa pensed with in light work.

The side bars 6 and 10 of the screw may have grooves 18, as usual, towork on guideribs at the sides of the window-frame.

It will be seen that the sash, shutter, or screen will fit close in theframe, so that no air or moisture can pass between the sash, &c., andthe frame, nor between the bars 7 and l0.

The device has also another valuable feature, in that it forms a supportfor the sash, shutter, inside blind, or screen'by the bearing of the barl0 against the window-frame. For this reason balance-weights, with theircords and sheaves, may be dispensed with.

Still another advantage is found in the device-namely, that the sashadmits of such construction that it may be removed from the frame at anytime by forcing the bar 7 in contact with the bar 10.

The operation of my device is as follows: The parts being tirstconnected, as described, the bar 10 is set into the usual groove in thewindow-frames and the sash grasped by the bar 6 and pressed toward thebar 10, causing the coil-springs 15 to contract and allow the IOO bar 7to be pressed in contact with the bar 10. When the parts are thuscontracted, the bar 6 may be placed in position in its groove in theframe, or the screw adjusted so the guidestrips rest in the grooves 18and the bar 10 allowed to move outward, and thus the bars 6 and 10 areheld tight against the windowframe.

By constructing a window sash, blind, or screen according to myinvention it may be placed at any desired elevation, and will remain inthat position Without the use of weights or cords. It may also be easilymoved into any other position.

The device also provides atight connection between the sash andWindow-frame, whereby dust, &c., is prevented from entering, and shouldthe sash or frame become shrunk or swelled from heat or rain the sashadjusts itself to the changedvconditions.

Il claim as my invention- 1. The combination, in a Window sash,- blind,or screen, of the bar 7, plates 8, and bar 10, suitably connected to theplates with springs forcing the bar outward, substantially as and forthe purposeset forth.

2. The combination, in a window sash, blind, or screen, of the bar 7,plates 8 secured therein, and a bar 10, adjustably connected to theplates by a pin passing therethrough and Working in Vslots in theplates, substantially as and for the purpose set forth.

3. The combination, in awindow sash, blind, or screen, of the bar 7,plates 8, secu red therein, bar 10, connected to the plates 8 by pins 11Working in slots 9 ofthe plates, and a spring 15, substantially as andfor the purpose set forth. I Y

4. The combination, with a Window sash, blind, or screen, of asidebar10, plate 8, forming a guide for the bar 10, and spring forcing thebar outward, substantially as set forth.

5. The combination, with a window sash, blind, or screen, of the plate8, bar 10, spring 15, and the movable plate b, forming abea'ring for theinner end of the spring, substantially as set forth.
